Since the images in the UTKface dataset were obtained from the internet, it is not clear if they are encoded in standard RGB using white point D65 or not.
However, we assumed all of these to be in standard RGB as this is considered to be the default color space for the internet [1]}.
The images collected for the remote ballistocardiography dataset were collected using a Panasonic GX85 camera with a default standard RGB color space.
The images from the Parkinson's disease postural tremor test were collected using the main camera of a Samsung S7 phone which also encodes them in standard RGB.
